RV670 supports DisplayPort and ATI is ready to showcase this marchitecture in early January. The key point is that you need a monitor with this port in order to sell the graphics with it, but it looks that we will have to wait at least a few more months before we are able to buy them.
It looks that DisplayPort is predominant and that it will take most of the display market and graphic cards are ready to offer whatever you want.
Dell is one of the key supporters for the DisplayPort and it has some impressive plans to move all its notebooks and monitors to this new marchitecture. We are sure that we will see many in early January at CES.
